Lava lake - Wikipedia
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified (sometimes referred to as frozen lava lakes).
Lava Lakes - U.S. National Park Service
Lava lakes are lakes of molten or solidified lava in volcanic craters or depressions. They may form when a vent or crater becomes partially filled with molten lava. Most lava lakes are comprised of basaltic lavas.
Inflation Structures, Lava-Rise Plateaus & Inflation Pits
Inflation pits (also known as lava-rise pits) are uninflated zones of an inflated flow where the solid upper crust and hardened bottom surface were not separated by further injection of liquid lava. They form when a lava encountered a topographic obstacle so that the flow is thinner above it.
Lava tube - Wikipedia
A lava tube, or pyroduct, [1] is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave.

Zuni-Bandera Field and McCarty's Lava Flow Field
Youthful volcanic field; the McCartys lava flow is one of the youngest and longest lava flows on the continent. Alkali basalt, hawaiite, tholeiite cones, craters, and fissures. The volcanoes and associated lava flows in this area are among the youngest eruptions in New Mexico.
Lava‐Rise Plateaus and Inflation Pits in the McCartys Lava Flow …
Apr 27, 2020 · Inflation pits commonly include blocky material on their floors and may superficially resemble skylights formed by the local collapse of a lava tube's roof, but the origin of the pits can be conclusively determined by identifying lava-wedges within the walls of the structure.
Lava cave - Wikipedia
Pit craters form when magma that doesn’t quite reach the surface drains to form a void, and the ground above it slumps. These huge open-air pits, with their sheer walls, are analogous to some of the large shafts that formed by solution, and typically require a roped descent for exploration.
